Judah kept their genealogies better than any other tribe, a special providence of God, to clear the line of Christ. Hezron was one of the seventy who went down to Egypt with Jacob, and his family multiplied there as the oppressed families did; the Jews say he married three times because he burned to see posterity in the house of Pharez, from whom the Messiah would come.

Commenting on 1 Chronicles 2:18-55
Caleb here is plainly a shortened form, so all exegetes recognize it. The first half of verse eighteen is obscure and likely corrupt in the text. We must read it as 'Caleb begat with Azubah' and separately 'with Jerioth', one was his wife, the other a secondary partner, and only one wife's sons are listed before her death in verse nineteen.
